+# Gemma 3 4B IT — Vindex (f16)
+
+FFN knowledge index extracted from `google/gemma-3-4b-it` using LARQL.
+
+Treats transformer FFN weights as a queryable knowledge graph — retrieval via dot-product graph walks against gate vectors, no matrix multiplication.
+
+## Usage
+
+```sql
+larql> USE "hf://chrishayuk/gemma-3-4b-it-vindex";
+larql> DESCRIBE "France";
+```
+
+## Contents
+
+- 34 layers, 348.2K features
+- Gate vectors, embeddings, down features/weights
+- Attention weights, norms, tokenizer
+- Probe-confirmed feature labels
+- f16 precision
+
+## What is a vindex?
+
+A vindex decouples a model's knowledge from its inference machinery. The FFN weights become a queryable graph — DESCRIBE returns typed knowledge edges, WALK traces activation paths, INFER runs graph-walk inference at 31 tok/sec on CPU.
+
+See [LARQL](https://github.com/chrishayuk/larql) for the full engine.
